Why do Guinea Pigs have red eyes and a rough guide to eye problems

By Clive Curry - The Willow Vet Clinic

This was prompted by some recent misconceptions about pink eyed animals !!

The pinkness is essentially an absence of pigment, which means light from inside the eye tends to reflect the pink colour of tissues behind the retina. Its like a horse with a wall eye, the pupil of a liver and white springer spaniel or a siamese cat. As far as we can tell these pigment differences have no effect on vision. The density of photoreceptor tissue and its sensitivity is unaffected by the absence of pigment. As far as we can tell guinea pig vision is myopic (short-sighted) with the emphasis on monocular all round vision.If your going to get eaten a lot, that is more important than the binocular vision of two forward facing eyes in a hunter/carnivore.

The eye is essentially pauangiotic, that’s basically like a horse, a retina without obvious blood vessels or a noticeable hotspot like a tapetum. This means its not possible to make judgments about a guinea pigs visual ability or lack of it with an ophthalmoscope.
